Figure 3. DENV and ZIKV neutralising antibody titres in cord plasma.
FRNT 90 antibody titres measured against ZIKV MR766 strain in cord plasma from cases and controls are shown in ( A), including p value from statistical comparison using the Mann-Whitney U test. For ZIKV FRNT 90 seropositive samples (n=68) the corresponding FRNT 90 antibody titres against a local DENV-2 isolate are shown in ( B). The dashed line represents the assay limit of detection.
